Hello everyone, I just bought the Utracer6 kit from Ronald (I'd like to thank him for his fantastic work).

I'd like to test the 829B tube, but I don't know how to connect the Pu1 and Pu2 connectors. Can anyone help me?

Thanks.

You'll have to measure one section at a time. From the data sheet I see that the cathodes, screens, and suppressors are common, but the heaters can be separated. I think I would connect for example PU1, g1 Unit 1 (pin 6), g2 (pin 3), and k (pin 4) as usual, and connect pins 5 and 7 to the heater supply (6.3V at 1.125A). To test the other section connect PU2, g1 Unit 2 (pin 2), and pins 5 and 1 to the heater supply.

Thank you very much for your reply. I will first finish the tube tester and then test the 3E29 tube and will share the information with everyone here. Thank you.
